To solve these problems, NET/ROM, a PROM-based networking program that
installed inside some TNC models, and a number of derivatives of NET/ROM
(e.g., G8BPQ, X1J, KA-Node, K-Net) were developed. These networking pro
-
grams provide the user connecting to a station via one of these nodes with a
choice of pathways to other packet stations and with lists of stations heard.
NET/ROM and several of its derivatives provide for automatic routing of your
connect request - much like the phone system today routes your long distance
calls. Others, such as the KA-Node, assist you in building a pathway by allowing
you to connect to each node in turn through the pathway. All of the nodes correct
the “end-to-end” acknowledgment problem mentioned above. This is accom
-
plished by building the pathway with a number of individual “local” connecting
links; that is, each link in the pathway is considered a connect and all acknowl
-
edgments of packets are kept local. Hence, if only one link of a pathway (chain)
is troublesome, the local nodes take care of it.
The following material is provided to assist you in configuring your KA-Node
and telling others how to connect to and use it. A listing of the node commands
for users follows.
Configuring Your KA-Node
The following commands are used to configure your KA-Node: NUMNODES,
MYNODE, NDWILD, and KNTIMER.
In order to set your TNC for use as a KA-Node several conditions must be met.
First, you must allocate the number of circuits (channels) you wish to allow
through the KA-Node (see NUMNODES). Each circuit consists of an “IN” and
an “OUT” side. Secondly, the callsign assigned to the KA-Node (MYNODE)
must be different from the callsign used for you (MYCALL), your alias
(MYALIAS), the PBBS (MYPBBS), and remote access (MYREMOTE). By de

fault, your TNC has set MYNODE to your callsign with an SSID of -7.

To cause your KA-Node to accept a connect request to any SSID of the
MYNODE callsign (except those mentioned above), set the NDWILD command
ON.
Packets passing through your KA-Node are monitored unless your MYNODE
callsign is included in the SUPLIST, if turned ON. If it becomes necessary to dis

connect a station from your KA-Node, you can issue the command DISCON
